To view the discussion, visit: https://community.jboss.org/message/761402#761402 -------------------------------------------------------------- The location of the jboss-service.xml doesn't appear to make a difference.  Step-debugging through the MBean's start() method, it looks like the TCCL is set in such a way that I don't have a chance of getting at my deployment's resources.  Specifically: public void start() throws Exception {   // ...   final ClassLoader loader = Thread.currentThread().getContextClassLoader();   URL loginConfig = loader.getResource(...);   // ... } Inspecting loader at this point gives:   ModuleClassLoader for Module "ucs.jb4compat:main" from local module loader @23e8f4e1 (roots: /opt/software/sag/sag_dev/modules) IE the TCCL is the module's ClassLoader, not that of the EAR deployment.  To the best of my knowledge, I don't have any EAR classes available at that point from which I could grab an appropriate ClassLoader. Looking up the stack a bit, I see: // org.jboss.as.service.AbstractService: protected void invokeLifecycleMethod(final Method method) throws InvocationTargetException, IllegalAccessException {         if (method != null) {             final ClassLoader old = SecurityActions.setThreadContextClassLoader(mBeanInstance.getClass().getClassLoader());             try {                 method.invoke(mBeanInstance);             } finally {                 SecurityActions.resetThreadContextClassLoader(old);             }         }     } Which appears to stash the TCCL at that point and explicictly set it to the MBean's ClassLoader.  The stashed TCCL (old) at that point is "ModuleClassLoader for Module "org.jboss.as.sar:main" from local module loader @23e8f4e1 (roots: /opt/software/sag/sag_dev/modules)". I've tried repackaging my resource (login-config.xml) inside the ear as ear//lib/config.sar//META-INF/login-config.xml as well as ear//lib/config.sar//login-config.xml, but none of the ClassLoader's I have available within the MBean's start() method are anything related to my EAR or its contents. On a side note, I realize root-of EAR isn't expected to be in Classpath per EE spec, but I thought that contents of EAR/META-INF should be.  So in this case EAR/META-INF/login-config.xml would be equally accessible as EAR/lib/config.jar//META-INF/login-config.xml, assuming I had a ClassLoader with a view of the EAR.  Is that incorrect?  Granted the distinction is moot unless I can find an appropriate ClassLoader to pull from. Just by way of structure, here's what I'm working with at the moment: The EAR: /Work/ExactlyWatt/java/dist/server/deployments $ unzip -l ExactlyWatt.ear Archive:  ExactlyWatt.ear   Length     Date   Time    Name --------    ----   ----    ----         0  09-25-12 09:33   META-INF/       106  09-25-12 09:33   META-INF/MANIFEST.MF         0  09-25-12 09:33   lib/ 11378038  09-25-12 09:33   ExactlyWatt.war     55168  09-25-12 09:33   ExactlyWatt_ejb.jar ...       866  09-25-12 09:33   lib/config.jar (See below) ...     40161  09-25-12 09:33   lib/ydoclet-runtime.jar       568  09-25-12 09:32   META-INF/application.xml      1137  09-21-12 15:12   META-INF/exactlywatt-ds.xml      1050  09-24-12 15:26   META-INF/jboss-service.xml config.jar within EAR/lib: /Work/ExactlyWatt/java/dist/server/deployments/ear $ unzip -l lib/config.jar Archive:  lib/config.jar    Length     Date   Time    Name   --------    ----   ----    ----          0  09-25-12 09:33   META-INF/        106  09-25-12 09:33   META-INF/MANIFEST.MF        936  06-23-11 13:22   META-INF/login-config.xml   --------                   -------       1042                   3 files EAR/META-INF/jboss-service.xml: /Work/ExactlyWatt/java/dist/server/deployments/ear $ cat META-INF/jboss-service.xml <?xml version="1.0" encoding="UTF-8"?> <server xmlns="urn:jboss:service:7.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="urn:jboss:service:7.0 http://ucmsload.courtnet.org/dtds/jb7/jboss-service_7_0.xsd"> *  <!-- Note this MBean deploys & works properly.  It's accessing files on-disk in standalone/configuration rather than trying to pull from classloader.  -->*   <mbean code="ucs.jb4compat.SystemPropertiesService" name="jboss.util:type=Service,name=SystemProperties-ExactlyWatt">     <attribute name="URLList">configuration/exactlywatt.properties</attribute>   </mbean>   <mbean code="ucs.jb4compat.DynamicLoginConfig" name="sample-app:service=DynamicLoginConfig,domain=ExactlyWatt"> *    <!-- With or without "META-INF/" here makes no difference. -->*     <attribute name="AuthConfig">*META-INF/*login-config.xml</attribute>     <depends>jboss.util:type=Service,name=SystemProperties-ExactlyWatt</depends>   </mbean> </server> /Work/ExactlyWatt/java/dist/server/deployments/ear $ cat META-INF/application.xml <?xml version="1.0" encoding="UTF-8"?> <application xmlns="http://java.sun.com/xml/ns/javaee"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://ucmsload.courtnet.org/dtds/javaee/application_6.xsd"   version="6">   <description>ExactlyWatt Jar Index</description>   <display-name>ExactlyWatt</display-name>   <module><ejb>ExactlyWatt_ejb.jar</ejb></module>   <module>       <web>          <web-uri>ExactlyWatt.war</web-uri>          <context-root>/ExactlyWatt</context-root>        </web>   </module> </application> Note this particular attempt has jboss-service.xml directly in EAR//META-INF without a SAR file to wrap it.  If I change things to put jboss-service.xml inside EAR//config.sar//META-INF and add EAR//META-INF/jboss-app.xml with a <module><service>config.sar</service></module> and application.xml with <module><java>config.sar</java></module>, it makes no difference on any of this.  I still get the module's ClassLoader for TCCL in the MBean's start() method and have no access to the EAR deployment's contents. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/761402#761402] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
